OET interlinear 1SA 2:29

uW Translation Notes:

Note 1 topic: figures-of-speech / idiom

לָ֣⁠מָּה תִבְעֲט֗וּ בְּ⁠זִבְחִ⁠י֙ וּ⁠בְ⁠מִנְחָתִ֔⁠י

to/for=what despise in/on/at/with,sacrifice_of,my and,in/on/at/with,offering_of,my

Yahweh is using a common expression of his culture to mean that Eli and his sons were treating his sacrifices with disrespect. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [Why do you treat my sacrifices with such disrespect]

Note 2 topic: figures-of-speech / rquestion

לָ֣⁠מָּה תִבְעֲט֗וּ בְּ⁠זִבְחִ⁠י֙ וּ⁠בְ⁠מִנְחָתִ֔⁠י

to/for=what despise in/on/at/with,sacrifice_of,my and,in/on/at/with,offering_of,my

Yahweh is using the question form for emphasis. If a speaker of your language would not use the question form for that purpose, you could translate this as a statement or as an exclamation. Alternate translation: [You should not kick at my sacrifice and at my offering …!]

Note 3 topic: figures-of-speech / hendiadys

בְּ⁠זִבְחִ⁠י֙ וּ⁠בְ⁠מִנְחָתִ֔⁠י

in/on/at/with,sacrifice_of,my and,in/on/at/with,offering_of,my

In other contexts, the words sacrifice and offering can refer to two different things. But here Yahweh is using them synonymously in a phrase that expresses a single idea by using two words connected with and. The word offering tells what kind of sacrifice Yahweh means. Alternate translation: [at the sacrifices that people offer to me]

Note 4 topic: figures-of-speech / yousingular

תִבְעֲט֗וּ & וַ⁠תְּכַבֵּ֤ד אֶת־בָּנֶ֨י⁠ךָ֙ & לְ⁠הַבְרִֽיאֲ⁠כֶ֗ם

despise & and,honor DOM sons_of,your & by,making_~_fat,yourselves

The pronouns you and yourselves are plural because the man of God is referring to Eli and his sons. The pronoun your and the verb honor are singular because the man of God is referring to Eli alone. Use the appropriate forms in your translation if your language marks that distinction.
